The portrait of a man in red chalk (circa 1510) in the Biblioteca Reale, Turin is widely accepted as a self portrait of Leonardo da Vinci. It is thought that Leonardo da Vinci drew this self-portrait at about the age of 60. The portrait has been extensively reproduced and has become an iconic representation of Leonardo as polymath or "Renaissance Man".The portrait is drawn in red chalk on paper. It depicts the head of an elderly man in three-quarter view, turned towards the viewer's right. The subject is distinguished by his long hair and long waving beard which flow over the shoulders and breast. The length of the hair and beard is uncommon in Renaissance portraits and suggests, as now, a person of sagacity.
